I assume its a bit difficult to get started. My brain works very low level. And communicating the main points is sometimes more difficult than one assumes. I am not as gifted as Cage when it comes to break down technicals. But lets try and discuss all issues by mail or in the thread ;) To clarify it a bit. You have to think of positions of the parameters that you want to optimize. If you have a SideSide that you want to optimize for [-50,0,50] and you have a bend you want to optimize for [-75,0,75], then you have to specify these values and create JCMs for -75/-50, -75/0, -75/50 0/-50, 0/0, 0/50 75/-50 75/0, 75/50 If the parameters a dialed to an intermediate value (e.g. -35/60) then multiple Fx diales will become active, but none of them at 1.0, rather each one a bit. Then you CANNOT teach it. You have to specify the key values at the positions you are going to make a JCM for. Only if you have a Fx dial that maxes out to 1.0 at the desired position you can create a JCM for this.
